hi there I was wondering if anyone can shed some light on this, I have a 02 golf gt tdi I wanted the exhaust to sound better so I removed the rear box and had pipe made this sounded ok ,then I decided the cat needed to go, couple of my mates have same cars with cats etc removed there pretty quiet with nice whistle at the back and a flutter when they lift off, mine how ever sounds like at best .... a tractor with no flutter just extreme noise very frustrating as they have exactly the same cars.any ideas would be much appreciated cheers mark
